Possible wheel upgrade

Well I'm looking to possibly upgrade my steelies for Alloys, question is what are my options size wise.

My current wheels are 205 55 16 but am looking to increase without putting my speedo out.

I have seen Various alloy wheels on good old Ebay but thinking to keep with Vx wheels.

I have to admit I love the Vx snowflakes but the price tag seen a set going for £700 but not sure thinking above my budget.

anyways what do you guys think I could upgrade to 17, 18 or 19's I'm assuming vx could re-calibrate the speedo if needed.

Cheers

Would Zaf A snowflakes look right on a Zaf B, was thinking has this been done before.

Alot of people say that it puts the speedo out but I don't think it does in most cases.

When u put bigger wheels on you end up with a lower profile tire this keeps the total height of the wheel the same as a standard wheel and tyre.

I have 19s on mine with no issues. I think 245/35 r19s

At this moment in time I am undecided on size but for now the steelies will be staying definately food for thought.

Was considering the VXR style ones but not 100% convinced the ones I am looking at are genuine.

What do you guys think?

dont seem too badly priced, look nice

just go the full hog and get a set of 19" snowflakes, probably get a set with tyres in resonable condition for about the same money.
